The results provide early evidence linking diet to human microplastic exposure levels.
Microplastics in human feces: a pilot study exploring links with dietary habits
Researchers analyzed fecal samples from 18 people in Norway and found microplastics in 17 of them, with polypropylene being the most common polymer, but found no significant link between seafood consumption and microplastic levels. The results suggest that dietary habits alone do not determine exposure, and that microplastics may enter the body through many everyday sources beyond food.
Microplastics in stools and their influencing factors among young adults from three cities in China: A multicenter cross-sectional study
In a study of 78 college students across three Chinese cities, microplastics were detected in the stool of nearly every participant, with a median concentration of about 55 micrograms per gram. People who ate more takeout food had significantly higher microplastic levels in their stool. This is one of the first studies to measure the actual mass of microplastics passing through young adults' digestive systems, confirming that diet and food packaging directly influence human exposure.

Microplastics were also found in the seafood, staple foods, drinking water, table salt, and toothpaste regularly consumed by these participants. The study provides direct evidence that microplastics are entering the human body through multiple everyday sources in coastal populations.
Take-out containers as nano- and microplastics reservoirs: Diet-driven gut dysbiosis in university students
Researchers analyzed stool samples from 24 university students and found microplastics in every sample, with students who frequently ate from plastic take-out containers having significantly higher levels. The most common plastic type was PET, likely from food packaging. Higher microplastic levels were associated with changes in gut bacteria composition, suggesting that everyday habits like eating take-out food could disrupt gut health through microplastic exposure.
Exploring the determinants of micro- and nanoplastics exposure among adults in Barcelona, Spain
Researchers quantified micro- and nanoplastic concentrations in stool, urine, tap water, and food samples from 50 healthy adults in Barcelona, Spain. They estimated a daily intake of 1.53 micrograms per kilogram of body weight, mainly from food, with polyamide, polyethylene, and polypropylene as the most frequently detected polymers. The study found that short-term diet better reflects microplastic exposure than long-term dietary habits, and that plastic additives in the body did not correlate with microplastic levels, ruling them out as proxy measurements.
Plastics, diet and human health: Accurately assessing exposure in adults.
This research project is developing methods to accurately measure how much plastic people are exposed to through their diet, including microplastics from food packaging. The study examines whether reducing plastic food packaging can lower dietary plastic exposure and simultaneously improve diet quality. It matters because understanding true dietary exposure is a prerequisite for assessing health risks from microplastics in food.
A review on microplastics in mammalian feces: Monitoring techniques and associated challenges
Researchers reviewed how microplastics appear in the feces of humans, dogs, cats, and marine mammals, finding PET plastic to be the most common type across species. Analyzing feces offers a non-invasive way to track how much plastic organisms are ingesting, which could help guide environmental health policies.
Relationship between microplastics in stool, diet, and inflammatory markers in healthy Japanese individuals
Researchers investigated the relationship between microplastics found in stool, dietary intake, and inflammatory markers in healthy Japanese individuals who typically consume a diet high in vegetables and seafood. The study explored how different types of microplastics in the intestinal tract may correlate with gastrointestinal inflammation and oxidative stress markers. The findings contribute to understanding how dietary habits influence microplastic exposure and its potential effects on gut health.
Analysis of Microplastics in Human Feces Reveals a Correlation between Fecal Microplastics and Inflammatory Bowel Disease Status
Researchers analyzed microplastics in the stool of patients with inflammatory bowel disease (IBD) and healthy volunteers, finding that IBD patients had significantly higher concentrations of microplastics in their feces. PET plastic and polyamide were the most common types found, likely originating from food packaging and dust. The positive correlation between microplastic levels and IBD severity suggests that microplastic exposure may be linked to gut inflammation, though it is not yet clear whether the plastics contribute to the disease or the disease causes more plastic retention.
Association between microplastics exposure and gut microbiota and metabolites in older adults: A cross-sectional study
Researchers analyzed fecal samples from 45 older adults to assess the relationship between microplastic exposure and gut microbiota. They found an average of 70 microplastic particles per gram of feces, primarily PVC, butadiene rubber, and polyethylene, and observed that microplastic exposure was associated with changes in gut microbial diversity and metabolite levels. The study suggests that microplastics may influence gut health in older adults by altering bacterial community composition and metabolic pathways.
